101 million Indians now live with diabetes. But what if rising heat, smog, and storms aren’t just making life uncomfortable… but actively worsening your blood sugar? A new global review reveals how air pollution (PM2.5) and extreme heat can mess with insulin, trigger inflammation, and even alter how your body absorbs medicine. In Chennai and Delhi, just 10 extra micrograms of pollution per cubic metre meant a 22% higher diabetes risk. And it’s not just about getting sick. Heat can destabilize insulin stored at home. Floods can shut clinics for months. No refills? No tests? That’s how a storm turns into a medical emergency. With only 8-10% of households having AC, and pollution covering nearly everyone, climate isn’t just an environmental issue; it’s a health time bomb. The science is still growing, but the warning is clear: your body’s fight against diabetes just got harder; and the sky is partly to blame.
